Abstract: PURPOSE:To reduce the loss of reflection by an air layer by filling the gap between a diffusion plate and a light guide plate and the gap between the light guide plate and a reflecting plate with transparent resin layers respectively. CONSTITUTION:The light emitted by a light source 1 is made incident on the light guide plate 4 to travel in the light guide plate 4 while reflected totally and repeatedly by the border surfaces of the transparent resin layers 3a and 3b and part of the light striking a dot of a translucent diffusion material provided on the border surface between the light guide plate 4 and transparent resin layer 3 is reflected to enter the transparent resin layer 3a at an angle of incidence below the critical angle and passed through the diffusion plate 2 as it is to exit to the front of a back light. Further, the part of the light is transmitted through the dot to enter the transparent resin layer 3b and reflected by the reflecting plate 5 to enter the light guide plate 4 again, and the light is passed through the transparent resin layer 3a, because the incident angle is lower than the critical angle at the border surface between the transparent resin layer 3a and the light guide plate 4, and is passed through the diffusion plate 2 to exit to the front of the back light; and the brightness on the back light surface is increased by specifying the refractive indexes of the light guide plate 4 and transparent resin layers 3a and 3b.

Title: Separation of magnetic body using magnetic field
Inventor: TAKEUCHI MAKOTO
IPC: G01N30/02
Filed: 1983-09-29
Abstract: PURPOSE:To make it possible to separate and extract the arbitrary solute in a solution while largely distinguishing the same from the other solute, by cyclically changing the intensity of a magnetic field in synchronous relation to the flow speed of a liquid to be separated. CONSTITUTION:A specimen solution is flowed through a passage 4 in which ferromagnetic bodies 7a-7n magnetically separated to each other are arranged at constant intervals and cyclic magnetic fields are applied to a direction at right angles to a flow direction. The paramagnetic substance being a solute to be detected in the specimen solution is trapped to the end surfaces of the ferromagnetic bodies 7a-7n by the application of magnetic fields. When the magnetic field is turned OFF, the trapped paramagnetic substance begins to move at the slowest speed of the streamline distribution of the developed liquid of the specimen solution and, when reaches the position of the next ferromagnetic body, receives the application of the magnetic field to be again trapped. By succeeding this operation, a max retention time is obtained. On the other hand, particles having no magnetic property and particles taking no synchronism are flowed at a speed near to that of the fluid without receiving the influence of the magnetic field and, therefore, only the trapped particles are efficiently separated.

Title: Measuring device of verdet's constant
Inventor: TANABE KUNIO
IPC: G02B27/28
Filed: 1987-07-21
Abstract: PURPOSE:To measure the Verdet's constant with high accuracy, by employing a super- conductive coil for the coil wound around a material to be measured so as to generate magnetic field in a direction to which the linearly polarized light proceeds. CONSTITUTION:Light from the light source is inputted to a polarizer 1 to be a linearly polarized light which is then incident upon an object 2 to be measured. The object 2 is wound by a superconductive coil 5, so that the magnetic field is generated in a rectilinear direction of light. Therefore, the linearly polarized light is rotated in its polarization direction and enters a polarizer 4 the strength of which is observed by an optical detector 7. The strength of light is changed based upon the rotation of the shaft of the polarizer 4. Therefore, by adjusting the strength of light to be maximum, the rotational angles at that time can be obtained. Since the length of light passing through the object 2 and the strength of the magnetic field generated by the coil 5 can be measured in advance, the Verdet's constant can be calculated by a predetermined formula. the super-conductive coil is employed for generating the magnetic field, and accordingly a large magnetic field can be generated. Therefore, even if the Verdet's constant is small, or the object 2 is short, the rotational angles can be made large, whereby the Verdet's constant can be obtained with ease.

Title: Current source circuit
Inventor: MIKI TAKAHIRO
IPC: H03K5/12
Filed: 1989-07-12
Abstract: PURPOSE:To reduce the settling time of an output voltage by varying an output current for a transient response period and outputting a current being the sum of a predetermined output current and an excess current in addition for a prescribed period, stopping the supply of the excess current and outputting only the prescribed current. CONSTITUTION:When a signal S at a terminal 2 changes from L to H, an output signal S1 of a sub current drive circuit 12 changes from L to H, switches 5, 8 are turned on and a sum (Ioo+Io1) of an output Ioo of a current source 1 an and output Io1 of a current source 7 is applied to a resistor 10 and a parasitic capacitor 11 via a terminal 3. Since the charge supplied to the parasitic capacitor 11 per unit time is much, the output voltage rises quickly. when the output voltage approaches an object IooR, only the output signal S1 of the sub current source drive circuit 12 changes to L again. Thus, the output voltage is settled to IooR. Thus, the voltage reply period is reduced.
